Addressing the Impact of Solar Modulation Systematic Uncertainties on Cosmic-Ray Propagation Models
Isabelle John, Alessandro Cuoco, Mattia Di Mauro
We perform a comprehensive analysis of cosmic-ray propagation using the time-dependent AMS-02 flux measurements covering a full solar cycle, with particular emphasis on the role of…
First Observations of Solar Halo Gamma Rays Over a Full Solar Cycle
Tim Linden, Jung-Tsung Li, Bei Zhou +4
We analyze 15 years of Fermi-LAT data and produce a detailed model of the Sun's inverse-Compton scattering emission (solar halo), which is powered by interactions between ambient c…
Every Nearby Energetic Pulsar Is Surrounded by a Region of Inhibited Diffusion
Isabelle John, Tim Linden
The H.E.S.S. telescope has recently detected the total electron-plus-positron () flux up to 40 TeV, finding it to be a featureless and steeply-falling power-law above 1 TeV…
Dark Branches of Immortal Stars at the Galactic Center
Isabelle John, Rebecca K. Leane, Tim Linden
We show that stars in the inner parsec of the Milky Way can be significantly affected by dark matter annihilation, producing population-level effects that are visible in a Hertzspr…
Dark Matter Scattering Constraints from Observations of Stars Surrounding Sgr A*
Isabelle John, Rebecca K. Leane, Tim Linden
High resolution infrared data has revealed several young stars in close proximity to Sgr A*. These stars may encounter extremely high dark matter densities. We examine scenarios wh…
Pulsars Do Not Produce Sharp Features in the Cosmic-Ray Electron and Positron Spectra
Isabelle John, Tim Linden
Pulsars are considered to be the leading explanation for the excess in cosmic-ray positrons detected by PAMELA and AMS-02. A notable feature of standard pulsar models is the sharp…
Cosmic-Ray Positrons Strongly Constrain Leptophilic Dark Matter
Isabelle John, Tim Linden
Cosmic-ray positrons have long been considered a powerful probe of dark matter annihilation. In particular, myriad studies of the unexpected rise in the positron fraction have deba…
